Abstract

Aspects of online camera calibration for autonomous driving systems are described herein. The aspects may include a wheel odometer configured to measure a current speed of a moving vehicle, a speed monitor configured to determine that the current speed of the moving vehicle is high or low, and a camera calibrator configured to calibrate, while the vehicle is moving, at least one front camera of the moving vehicle according to a position of a vanishing point of two lane lines when the current speed is high. When the current speed is low and the vehicle is still moving, the camera calibrator may be further configured to calibrate multiple side and rear cameras of the moving vehicle according to a pose graph that includes relative poses of the multiple side and rear cameras.
